I did:

• restart the app
• checked and raised mem for the container to 2.46G
• checked ps, nothing special
• raised "MaxRequestWorkers" to 50 as mentioned here
• onlyoffice document server is responding

Since I only realised the error after the latest app-update, I went backt to cldr.-nc. v4.17.3 without change.

• NC-desktop is working.
• weblogin does not work

CLDRN is direct attached to Internet - same setup since years.

[nebulon]

The cron job error looks a bit like an installed plugin is incompatible with the nextcloud version.

[girish]

@chymian Looks like some issue in the files reader app - https://apps.nextcloud.com/apps/files_reader . Please disable that app following instructions at https://docs.cloudron.io/apps/nextcloud/#fixing-a-broken-install

[girish]

There's an error in nc 26 itself as reported upstream - https://github.com/Yetangitu/files_reader/issues/5

[necrevistonnezr]

You should consider not to provide support for Nextcloud instances with apps that are not provided and recommended by Nextcloud itself.

It should ALWAYS be the first step to disable all non-stock apps and restart Nextcloud to check whether any error persists. If it does not, the problem is - as in 99,9 % of all cases - an incompatible app.

[chymian]

remarkable behavior:
login via web does not work at the moment.
open the website via the nextcloud-desktop client does work and one is logged in.
but then, password-verification i.e. for module-update does again not work.

@nebulon your hint with the incompatible apps was true both problems.

• the login problem. which went away after deleting dropit
• and the cron pbl. as well, after disabling Reader (ebook reader)
• and there was a recommended app, which also threw errors: `group-folders'
  I leave it here for reference

thanks again
